At this time, there is a nice list of about 18 end game dinosaurs which are the upper echelon of battle dinosaurs that you want to use at the end.
I apologize for spelling mistakes and any other mistakes at this time.
These in no particular order are a front 9 of
Indoraptor, Spinotasuchus, Utarinex, Trykosaurus, Tentorex,. Diloracheirus, Erlidominus, Thoradolosaur, Dracorex Gen 2.
And a back 9 of
Stegodeus, Monomimus, Monostegotops, Diorajasaur, Magnapyritor, Tuormaloch, Tragodistis, and Tryostronix. Arguments can be made for Megalosuchus.
As you climb up the rankings you will see a migration from the back 9 to the front 9 but any of these can be considered solid members to a top 100 team.
Why did I make this list? It is to help break down, what dinosaur ingredients originate the most from the 4 zones that help make the top end game dinosaurs.
Zone 1. Deioncheirus, Megalosaurus, Dilophosaurus, Sinosecratops, Dimetrodon, and Kentrosaurus. It also has Posimetrodon as a hybrid…
Zone2. Has Dracorex generation 2, Gorgosaurus, Dracorex, Tenontosaurus, Ouranosaurus, Pyroraptor, and a hybrid of Stegaceratops.
Zone 3. Has Allosaurus, Postosuchus, Tuojiangosaurus, Monolophosaurus , Erilkosaurus, and a hybrid Spinoraptor.
Zone 4. Has ParaSaurolophus, Spinosaurus, Anklysosaurus, Rajasaurus. The hybrid is Gorgosuchus.
So there is a very strong argument that Zone 1 is the best, followed closely by Zone2 and then Zone 3. As for Zone 4. At least you can build up the Suchotator.
